Abstract
The invention discloses a novel digital display intelligent instrument, in particular to a special digital display intelligent instrument used for an electric warm air blower and a unit. The novel digital display intelligent instrument is provided with a blower fault warning and automatic power-off system. The novel digital display intelligent instrument is characterized in that the blower and a protective tube are connected in series, and connected with a relay, the relay is connected with an external power source and a microcomputer controller, and meanwhile the microcomputer controller is connected with an alarm and a current transformer. One end of the current transformer is connected with the microcomputer controller, and the other end of the current transformer is connected with a blower circuit. The novel digital display intelligent instrument has the advantages that when the novel digital display intelligent instrument is used for the electric warm air blower, if the blower breaks down, the protective tube will be switched off, the current transformer senses abnormity of a current and transmits the abnormity to the microcomputer controller, the microcomputer controller starts the alarm, the relay is disconnected with the external power source under the control of the microcomputer controller, and the blower is powered off. Dangerous accidents are avoided.
Description
Technical field
The present invention relates to one simple in structure, functional strong Novel digital display intelligent instrument, is specifically related to a kind of Novel digital display intelligent instrument, is mainly applicable to the instrument of electric warm-air machine and unit.
Background technology
society, electric warm-air machine has been widely used in various places.But since electric warm-air machine comes out, due to our improper use or machine itself breaks down, and the accident causing is of common occurrence, some meetings cause fire, and some meetings injure life, and this all brings great harm.Must improve the safety in utilization of electric warm-air machine, ensure people's the security of the lives and property.For this reason, the present invention has designed a kind of Novel electric warm-air machine and the special digital display intelligent instrument of unit.
Summary of the invention
The object of the invention is the safety in utilization in order to ensure electric warm-air machine, and reduce the generation of accident, a kind of novel dedicated digital display intelligent instrument is provided.This instrument has fan trouble and reports to the police and automatic circuit break function.
The technical solution adopted for the present invention to solve the technical problems is:
The fan trouble of this digital display intelligent instrument is reported to the police and the feature of auto-power-off system is: blower fan and protective tube are cascaded, and be connected with relay, relay is connecting power supply and microcomputer controller, and meanwhile, microcomputer controller has connected alarm summation current transformer.
Described current transformer one end is connected with microcomputer controller, and the other end is connected with protective tube and blower fan circuit.
The invention has the beneficial effects as follows: in the time that electric warm-air machine uses this instrument, if blower fan breaks down, protective tube will disconnect, and current transformer senses current anomaly, is transferred to microcomputer controller, microcomputer controller starts alarm, reports to the police.Microcomputer controller pilot relay disconnects external power supply, fan auto-breaking simultaneously.Improve the security of electric warm-air machine.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Accompanying drawing is electrical principle schematic diagram of the present invention;
1 blower fan in figure, 2 protective tubes, 3 current transformers, 4 microcomputer controllers, 5 alarms, 6 relays, 7 external power supplys.
Embodiment
By reference to the accompanying drawings, a kind of its fan trouble of Novel digital display intelligent instrument is reported to the police and is comprised that with auto-power-off system blower fan 1 is being connected protective tube 2, protective tube 2 is connecting current transformer 3, current transformer 3 connects microcomputer controller 4, microcomputer controller 4 is connecting alarm 5 and relay 6, and relay 6 is connecting blower fan 1 and external power supply 7.
This Novel digital display intelligent instrument is in actual use procedure, if when blower fan 1 breaks down, protective tube 2 disconnects, current transformer 3 senses current anomaly, abnormal signal is transferred to microcomputer controller 4, and microcomputer controller 4 starts alarm 5, sends alerting signal.Microcomputer controller 4 simultaneously, signal transmission makes relay 6 disconnect external power supply 7, thus fan 1 auto-breaking.Avoid the generation of peril.
The technology contents of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
It should be noted that, under the instruction of this instructions, those skilled in the art make any substitute mode that is equal to, or obvious variant, all should be within protection scope of the present invention.
Claims (2)
1. a Novel digital display intelligent instrument has fan trouble warning and auto-power-off system, it is characterized in that: described blower fan and protective tube are cascaded, and be connected with relay, relay is connecting external power supply and microcomputer controller, meanwhile, microcomputer controller has connected alarm summation current transformer.
2. Novel digital display intelligent instrument according to claim 1, is characterized in that: described current transformer one end is connected with microcomputer controller, and the other end is connected with protective tube and blower fan circuit.
